Activities That Require Big Forearms

Big forearms are usually associated with a powerful grip. The greater the cross-sectional size of a muscle, the more force it can exert. Your forearm muscles are also responsible for flexing, extending and rotating your wrists, and some also affect your elbow. While Popeye's huge forearms were attributed to eating lots of spinach -- which he needed to fight the bad guys -- there are plenty of real-life activities that require big forearm muscles.

  1. Rock Climbing

    • A rock climber's life can literally hang on the strength of their forearms. Holding a tiny rock outcrop can mean the difference between climbing upward or falling downward. Climbers often have very well develop forearm muscles because of climbing and the training exercises they do to increase climbing performance. Fingertip pullups using a campus board are an effective way to strengthen your fingers for climbing while developing big forearms.

    Grappling

    • Grappling is a technique used in a number of martial arts including judo, jiu jitsu and wrestling. Grappling is grabbing and holding your opponent with a view to getting him in a disadvantageous position from which you can then press the tactical advantage. Grappling requires and develops a vice-like grip and large, powerful forearms.

    Swinging a Sledgehammer

    • Swinging a sledgehammer or ax is a total-body activity, but the end of the kinetic chain is your grip on your hammer or ax handle. If you do not grip the striking implement tightly, it can twist on impact, so strong hands are a must. Using a hammer or ax will strengthen and develop your forearms and some people actually perform these manual labor activities for exercise. Striking accuracy depends upon a good aim and forearms big enough to swing the heavy tool directly at its target.

    Deadlifting

    • The deadlift is a strength-building exercise and also the third and final lift contested in powerlifting. Because deadlifting uses virtually every muscle in your body, very heavy weights can be lifted. However, you have to be able to keep hold of the bar, which requires and develops a powerful grip and muscular forearms. The current world record is more than 1,000 pounds -- and that's some serious forearm strength.

    Arm Wrestling

    • Arm wrestling requires a lot of forearm strength as competitors try to get into a mechanically advantageous position and press their opponents hand to the table. This can result in bigger forearm muscles. It is not uncommon for arm wrestlers to have one forearm bigger than the other, although a balanced approach to training, in which both arms are worked equally, is best.
